摘要:
Synthetic resin structural members (11,11a) are inserted into a hollow joint member to abut each other in the joint member. A bearing-pressure damping member (15) is fitted into each bolt hole formed in the members. The axes of bolts (16) fitted in the holes extend alternately in mutually perpendicular directions. Due to damping action resulting from elastic deformation of the damping members, a load is substantially evenly disitributed over all the bolts to prevent concentration of the load on some of the bolts. The arrangement of the bolts with their axes extending alternately in mutually perpendicular two directions shortens the length of the joint member.
